OILER Filed Feb. 21, 1958 3 Sheets-Sheet 3 Inventor FZZQQ c/re By 5m Aitorneys I Patented Jan. 31, 1939 UNITED STATES PATENT OFFICE 3 Claims.

The present invention relates to new and useful improvements in oilers and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character embodying a pump of a novel construction and arrangement whereby the oil or other fluid may be conveniently discharged under air pressure.

Another very important object of the invention is to provide an air pressure oiler of the aforeld mentioned character comprising a nozzle of such construction that the oil or other fluid may, if desired, be discharged in the form of a spray.

Other objects of the invention are to provide an oiler of the character described which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact, light in weight and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a top plan view of an embodiment of the invention.

Figure 2 is a view in side elevation of the device with portions thereof broken away in section.

Figure 3 is a vertical sectional view, taken substantially on the line ll-3 of Fig. 2.

Figure 4 is a view principally in side elevation but partially in vertical section of the upper portion of the device, showing the spray nozzle in use.

Figure 5 is a detail view in vertical longitudinal section through the spray nozzle.

Figure 6 is an end view of the spray nozzle.

Figure 7 is a detail view in perspective of one of the spray nozzle discs.

Referring now to the drawings in detail, it will be seen that the reference numeral l designates a container of any desired capacity for the re ception of the oil or other fluid. Screwed on top of the container l is a removable cap t. Adjacent the cap 2, a filling cap 3 is provided on the container II. Rising from the cap 2 is a neck A and threadedly mounted thereon is a removable packing nut 5. Mounted in the packing b and extending therethrough is a pipe 8. The construction and arrangement is such that the packing 5 is rotatable on the pipe 6 to permit said packing to be screwed on and off the neck A. The pipe 6 extends to a paint adjacent the bottom of the container I and has mounted on its lower or intake end a suitable screen i,

On the upper end of the pipe 6 is a housing 3 of suitable metal. Threadedly mounted in the housing 8 is a nipple or the like il having a valve 5 seat Ill formed on its inner end. A gasket ll prevents leakage at the joint between the nipple it and the housing 8. Threadedly mounted on the nipple 9 is a removable spout it. Threadedly mounted on the free end portion of the spout l0 i2 is a downturned, removable tip or nozzle it.

Projecting from the housing t is a tube it which is aligned with the nipple d. The reference numeral l5 designates a stem which extends slidably through the tube it into the housing 8 l5 and which is provided, on its inner end, with a valve it which is engageable with the seat it. As shown to advantage in Fig. 2 of the drawings, the valve it controls the oil passage in the nipple d. A coil spring ill in the housing t encircles 20 the stem l5 and is engaged with the valve it for yieldingly urging same toward the seat it. A packing it is provided for the stem it where it emerges from the outer end of the tube i l.

Fixed on the upmr portion of the container l 25 is an angular bracket it of substantially the shape shown to advantage in Fig. 2 of the drawings. Pivotally mounted on the bracket ill is a trigger in the form of a bell crank lever til having one end operatively connected to the valve stem it. W A handle M is provided beneath the bracket it.

It will be observed that one end of the handle 20 is fixed to the container l and that the other end of said handle is fixed to the bracket til.

Mounted in the lower portion of the container l 35 is an air pump which is designated generally by the reference numeral 22. The pump it? comprises a horizontal barrel 23 which extends into the container l beneath the handle M. A spring seated check valve it is provided in the discharge All end of the barrel 23. A removable cap 2% is threaded on the outer end portion of the barrel t3 and extending slidably through said cap is a rod 26. Mounted on the inner end of the rod 26 for reciprocation in the barrel it is a piston M 211. Pivotally mounted on the free end of the bracket i9 is a lever 28 the free end portion of which is operatively connected to the piston or plunger rod 2t of the pump 22. A coil spring it 50 encircles the rod 26 and has one end engaged with the cap 25 and its other end engaged with the free end portion of the lever 2% for returning the piston 21 of the pump it to the position shown in Fig. 2 of the drawings. A cushioning t spring 30 is provided in the outer end portion the barrel 23 for the piston 21.

It is thought that the operation of the device will be readily apparent from a consideration of the foregoing. By engaging certain of the fingers of one hand in the handle 2| and the palm of that hand with the lever 23, said lever may be conveniently actuated in a manner to operate the pump 22. On the inward stroke of the piston 21, air is forced under pressure from the pump barrel 23 into the. container I. When the pressure is removed from the lever 23 the spring 23 immediately returns said lever and the piston 21 to their former position ready .for the next stroke. The spring l1 normally maintains the valve [3 in closed position, thus preventing the discharge of the oil. When it is desired to permit the discharge of the oil, the thumb of the hand holding the device is used to actuate the lever 20, thus opening the valve it against the tension of the spring H. The oil in the container I is then forced by the air under pressure therein upwardly through the pipe 6 into the housing 3, then through the nipple 9, the spout l2 and the nozzle or tip l3. Of course, the discharge of theoil may be shut oil when desired by simply releasing the bell crank lever 20. The cap 2 and the assembly thereon may be conveniently removed to permit cleaning the container l or for other purposes. The oil may be conveniently placed in the container I by simply removing the filler cap 3.

The reference numeral 3| designates generally a spray nozzle which may be substituted for the spout II. The spray nozzle 3| comprises a conduit 32 which is adapted to be screwed on the nipple 9. Screwed on the forward end portion of the conduit 32 is a nipple 33 having mounted therein a screen 34. Threadedly mounted on the nipple 33 is a removable nut 35. Inner and outer discs 36 and 31, respectively, are mounted in the nut 35. Spacing gaskets 33 are provided for the discs 36 and 31. The outer disc 31 is provided with a single, centrally located port 33. The inner disc 36 is provided with a pair of discharge ports 40. The ports 40 are so arranged as to impart a whirling motion to the oil as it passes therethrough.

' 'It is believed that the many advantages of an oiler constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed. 7 a
